This location is very convenient to the airport; however, you must know ALL the hotels around Newark Liberty Airport DO NOT take you directly to the airport. They will drop you off at the AirTran, which will take you to the terminals. Therefore, you must know if you are taking an early flight (e.g., 6 am) ensure you sign-up for the shuttle and give yourself enough time. This is important to know and it was fine with me.
Also, the hotel offers overnight/extended parking, but it will cost you more than the Parking Spot, which is next door (if you get coupons etc.). I suggest you unload your car and then park next door.
NOTE: If your car is at the hotel for 30 mins or more they will charge you, which I think is not fair since they are not offering you a better parking price or competing with the Parking Spot next door.
